The garden's origins are inseparable from the moment Japan took control of Taiwan in 1895. A year later, the colonial administration established a nursery on this site, aiming to understand and exploit the island's remarkable botanical diversity. By 1921 it had a proper name -- the Taihoku Botanical Garden -- and by 1930, researchers had cataloged 1,129 species within its borders. The garden served science, but it also served empire: understanding which plants could be cultivated, exported, or turned to industrial use. World War II halted maintenance entirely. Trees grew unchecked, ponds silted over, paths disappeared beneath undergrowth. After Japan's defeat, new caretakers arrived with the Republic of China government, and the garden was rearranged and replanted. Today it is maintained by the Taiwan Forestry Research Institute, and its collection has swelled past 2,000 species -- nearly double the count from its prewar peak.

In 2019, the Taiwan Forestry Research Institute launched an initiative with an unusually poetic name: the Project for Future Green, or, in its Chinese shorthand, the Plant Ark Plan. The ambition was blunt -- to bring at least 75 percent of Taiwan's threatened plant species into ex situ collections before they vanished from the wild. When the project began, only 22 percent of those species were represented in any botanical garden. By 2022, that figure had climbed to 65 percent. Funding matched the urgency: NT$400 million, roughly US$13 million, spread across four years. New greenhouses were planned for the Taipei garden itself, giving fragile species climate-controlled refuge just blocks from the skyscrapers of downtown. The project made Taiwan one of the more aggressive players in global plant conservation, and the Taipei Botanical Garden its flagship site.

Walking the garden today, you pass through nine ponds, each designed for a different aquatic habitat -- lotus pools, fern grottos, wetland margins thick with reed. Specialty gardens cluster around themes: palms, conifers, medicinal herbs. But the two most striking features are architectural. A Qing Dynasty-era guest house, originally built in 1888 as a reception hall for imperial envoys, was moved here in 1933 and still stands as a designated historic structure. Nearby, the 1924 Herbarium -- the first purpose-built herbarium in Taiwan -- houses its vast collection of dried specimens alongside a seed bank. The juxtaposition is deliberate, even if unplanned: a building from the last dynasty and a building from the colonial period, both preserved inside a garden that keeps reinventing what preservation means.

The Taipei Botanical Garden now trades specimens and expertise with partners across continents. In 2022, memorandums of understanding were signed with the Mlyňany Arboretum in Slovakia and the Prague Botanical Garden in the Czech Republic, setting the stage for Central European species to appear in Taipei's beds and Taiwanese ferns to take root in Prague. The garden is also a member of Botanic Gardens Conservation International, plugging it into a global network of institutions racing to document and protect plant diversity before climate change and habitat loss outpace their efforts. For visitors, none of this geopolitical botany is visible. What you see is shade, water, birdsong, and a dense canopy that blocks out the city almost entirely -- a green pause in a metropolis that rarely offers one.
